Performance Specifications

Notes:

● Adjustability is 10% to 90% of full resistance value.

● Wattage is proportional to this adjusted resistance value.

Power Rating:

● Based on 25°C free air rating. The stated wattage rating applies only when the entire resistance is

in the circuit.

● Setting the lug at an intermediate point reduces the wattage rating by approximately the same

proportion.

● Example: If the lug is set at half resistance, the wattage is reduced by approximately one-half.
